Lichen
Lichens map the surfaces of bark in finely tuned patterns—each species occupying the microhabitat it can tolerate.
Sunlit ridges, shaded hollows, frost-catching fissures, and nutrient-enriched pockets all host their own specialists.
Together they form a quiet, living mosaic stitched into the trunk.
